In a first, US researchers have observed fractional excitons, a new class of quantum particles, that were only theoretically ...

Excitons, quasiparticles formed by an electron and a hole, transfer energy without a net charge. Physicist Ivan Biaggio ...

While their behavior in traditional semiconductors is well understood ... focuses on understanding the mechanisms behind exciton dynamics, quantum entanglement, and dissociation in organic ...

A new theoretical approach is proposed to explain the nature of the well-known narrow and ... based on quantum mechanics and Frenkel’s exciton theory, Egorov’s theory, based on quantum ...

Energy from an exciton in a quantum well can be transferred to a surface plasmon in a metal nanostructure if the surface plasmon has a similar energy. The roughness of the metal means that the ...

Scientists in Korea using 2D semiconducting materials discovered a new quantum state that could pave the way for more ...

However, an alternative process, multiple exciton generation (MEG), can occur in colloidal quantum dots. Here, some or all of the excess energy is instead used to promote one or more additional ...

The increased exciton binding energy results ... and color-tunable light sources, as well as sensitive and selective photodetectors for a wide range of applications, from displays to optical ...

It describes our researchers' vision of how to build a quantum computing circuit using light on a chip – a topic the team explored at the Royal Society Summer Science Exhibition. The basic underlying ...
